Application filed September 9, 1924. Serial No. 736,793.

The inventiony aims to provide a` radiator having considerableadvantages in economy and 'efficiency and adapted to be heatedfromvarious sources. The single figure 0f the drawing is a perspective view,partly in seclradiating structure of plates extending lat-erallyoutward. The radiating plates at one side of the chamber are preferablylmade from a' single continuous sheet bent to shape; and those on theopposite side from a similar sheet. Each sheet is thus formed intoplates 4 and 5, separated at their inner edges toform triangular spacesor chimneys for the upward circulation of air. At lt-heir inner edgeswhere theyl join the central chamber 2 there lis a short plate 6lbearing againstand preferably welded to the chamber so as to take theheat therefrom and conduct itk outward through the parts 4 and 5.. Theplates 4 and 5 of each pair comes together at their outer edges 7 wherethey are braced by longitudinal braces 8, preferably'in the form ofangle bars embracing the corners of the radiating 'strucf ture, and thusserving also to'prevent acci ldental contact of a person with suchcorners. The radiatin structure thus described differs inA detail lr ber2 is a pipe 9 for gas or similar fuel admitted throu h a cock 1 0. Thepipe or burner 9 has Ori ces 11, preferably at intervals correspondingtothe points of the heating chamber which lie opposite the searated'inner edges of the plates 4 and.

om that illustrated in my pre,l vious application 'but' is substantiallythe us when the gas is ignited the tiames will lie under the chamber 2and in the lower ends of the tri-1 angular chimneys formed by theplates4 and 5 and the sides of the chamber. For use with gas it isdesirable that hot water be supplied to the chamber. The pipe lfat thebottom and the pipe 12 'at the top may be used for introducing andwithdrawing such water or for permitting the escape of steam.

A third heating means is illustratedfconsisting of coils 13 of resistantwire suitably insulated and mounted in the outside spaces between theplates 4 and 5. A. cable 14 is illustrated for attachment to a socket toconnect Vthe electric heaters to the circuit.

I prefer to use for the heating chamber. and for the radiating structurea metal of great heat conductivity, such as copper, brass or zinc, whichare much superior to the ordinary metals, iron and steel. By usingcopper or brass in thin sheets I get a sufficient increase in eiiiciencyto compensate for the increased cost per pound. ,p For example, I mayuse plates ot' about one-sixty-fourth of an inch in thickness extendingoutward from one to 'six inches. The chamber ,2`should be narrow, asindicated. Radiators of thisA design and oi these materials anddimensions are particularly advantageous because they can be easilyequipped with 'gas boilers and electric heaters in the manner indicated,and these heaters can be located so as to secure the best application ofthe heat to wat'er carried in the chamber 2, the chamber being equallyadapted for steam or hot water circulation. l

The electric heaters stitfen the entire strucf ture against distortion,which is important with such thin sheet metal. Itjwill be observed thatthe gas flames and the velectric heaters are applied at alternate pointsalong the side of' the chamber. come up through the chimneys formed'bthe sides of the chambenwhile the electric heaters are inthe angularspaces which are open to the outside. It is contemplated that the.radiator shall be. equipped with boththese The gas flames `heatinginstrumentalities, as well as with couplings to which pipes may beattache@ for steam or hot water circulation. If any one of these methodsdoes not give the required y amount of heat. two, or eventhree, of themcan be used at the' same time, there being no interference between them.

An important feature of the invention is in the vertical extension ofthe transverse -plates formed by the corrugated structure.

. columns of air which are progressively heated on both sides byprolonged contact with the heated wallsof theducts and are thus impelledrapidlyupward so as t0 accelerate the circulation olf the heated aircolumns upward from the! ducts and throughout th room or inclosure to beheated. v L

The ducts between transverse plates which converge at their outer edgesare in fact fiues closed in cross-section and adapted to produce an evengreater draft upward than the spaces between such fiues; the draft beingslower in the latter because of the admission of cool air at the openouter side of the duct.

The actiontakes place either with or without 'water-fin the waterchamber 2, the edect of water'V therein being merely to maintain. a

store of heat for a certain length ofjtime' afterjhel electric currentis cut off.

The ducts act in the'same way when the heat is supplied from the fuelpipe or burner 9. This burner in fact constitutes a heatingl elementlocated solely at `the bottom 'of the ducts described; in contrast withthe electric heating devices which are .attached to the transverseplates not only at. the lower or- A tions of the latter, but throughoutt er height.' v i The result of, this structure of vertical ducts isthat instead of a relatively stationary or slowly rising and laterallydiffusing -overheated body of air around a heating element andunderheated air in the remainder of the room or inclosure, there isobtained a greatly accelerated vascent of warm columns of air throughthe heated duets and upward therev from and thus v'a forced circulationand distribution of evenly heated, air throughout the entire inclosure.y l Specific claims for the electricheater are not presented in thepresent application, being covered in a co-pending divlsionalapplication No. 331,347, filed January 9, 1929.

Though I[ have described with great particularity-of detailcertainembodiments ofI .myinventiom yet it is not to be understoodtherefrom that'the invention is restricted to thevparticular embodimentdisclosed. Various modifications may be made by those skilled in the artwithout departing from the invention as defined in the following claims.

What I claimy is: i

1. A combination heater. and radiator including in combinationa chamberfor a fluid heating medium, a radiating structure comprising verticallyextending plates mounted on the 'outer faces of said chamber and formingflues which are closed in cross section along the-sides of the chamber,electric heaters in contact with the outside of the chamber between saidfiues and a gas burner below said chamber with orifices registering withsaid fiues and alternating with said electric Y heaters along the lengthof the chamber.

2. A combination heater and radiator including incombinati'on a chamberfor a fluid heating medium having fiat vertical sides, Ka radiatingstructure ofplates engaging the sides of the chamber, extendinglaterally outvward and forming with the chamber wall vertical flueswhich are closed in cross-section and spaced apart from one another,electric kheaters located in the spaces .between the fiues and adjacenttothe chamber, and a gasv burner below the chambervwith orificesregistering with said flues and alternatingwith said electric heatersalong the length of thev chamber, so that the fiames passup the'uesbetween the electric heaters and are separated from 'said heaters by-the'plates 3. A combination heater and radiator including'incombination a chamber for a fluid heating medium, a radiating structurecomprising vertically extending plates mounted on the outer facesofsaid'chamber and forming verticalfiues alongthe sides of the cham-\ber and a burner below lthe chamber with orifices registering with saidflues.

4. A combination heater and radiator comprising a burner, a fluidchamber and a longitudinal series of transverse-plates fixed in relationto said burner and chamber, said plates being substantially free'ofintervening' obstructions and rising vertically from the burner to aheight relatively great compared to their width, and forming alongitudinal series of unirnpeded heated vvertical air ducts.

In witness whereof,-I have hereunto signed my name.
